Is it true that you connect better to people who are at the same status as you?

After a certain age, yes. That's because of the collective experiences you have in common to reach that stage. Your network completely changes at some point and you will be surprised when you look back. It only shows you have progressed. There is nothing wrong about it.

School and college friends are probably the last set of people whom we bonded without any prejudice. Especially school!
